COLLINS, OF CUYAHOGA FALLS, OHIO, ASSIGNOR, BY MESNEASSIGNMENTS, '10 MILLER RUBBER COMPANY INC., 013 WILMINGTON, DELAWARE,'A CORPORATION on DELAWARE WINDING MACHINE Original application filedDecember 14, 1926, Serial No. 154,748. Patent No. 1,687,607, datedOctober 16,

1928. Divided and this application filed April 27, 1928.

My said invention relates to winding means of the type used in slittingand rewinding machines and the present application is a division of anapplication filed by me in the United States Patent Office on the 14thday of December, 1926, Serial Number 154,748 which has matured into aPatent No. 1,687 607 Oct. 16, 1928.

One of the objects of the invention is to provide means by which theplural bands may be wound in such a manner as to avoid stretching thematerial unduly, and to roll it in such form that it will remain smoothand free from wrinkles.

Another object is to provide means to enable the ribbon spools to bereadily and collectively removed when sufficient quantities of ribbonhave been wound thereon.

A'further object isto provide simple and effective means for severingthe rewound portions of the ribbons from the unwound portions and toenable the ready attachment of such unwound portions to fresh spools andtheir convenient replacement in winding position.

With these and other objects in view the invention comprises the novelfeatures of construction and arrangement and combination of partshereinafter described and as set forth in the appended claims definingthe 1nvention.

What I at present consider the preferred embodiment of the invention isillustrated in the accompanyingdrawings in which:

Fig. 1 is a central vertical longitudinal section of a sufficientportion of the machine shown in my aforesaid application to afford anunderstanding of the invention.

Fig. 2 is a plan view thereof.

Figs 3 and l are respectively a plan and edge view of the guide strip28.

Fig. 5is a detailed elevation, partly in section, of the spool guide.

Fig. 6' is an end view of the bar 31.

Fig. 7 is a transverse vertical section of the bar and spool guideelement.

Figs. 8 and 9 are respectively a plan vlew and edge view of plate 35.

Figs. 10 and 11 are similar views of plate Referring by referencecharacters to this Serial No. 273,293.

drawing the numeral 27 designates an idle roll around which the ribbonspass after hav ing been formed by the slitting mechanism disclosed in myaforesaid application, and from which roll they are led to guides whichaccurately align them with the rewinding rolls. These guides are formedby a steel plate 28 Figs; 3 and 4: having two sets of smooth polishedslots 28 milled in its 0pposite faces, one set being one-half inch inwidth, and the other three-fourths inch and correspondingly placed.

, The plate is removable and reversibly held so that it may be readilyinverted to effect the change of width of guide. Small guide plates 28are secured to the fences between the slots so as to provide nearlyclosed guides for the ribbons.

This guide plate is located in close proximity to the winding mechanism,whch will now be described.

This comprises a pair of rolls 29 and 30 which are driven at a slightlygreater surface speed than the platen. roll 2 of the slitting mechanism,conveniently by a train of gearing from the platen roll shaft. .Therolls 29 and 30 are provided with knurled or roughened surfaces to exerta pulling or turning efiect on the ribbon rolls which are floatinglysupported by the rolls 29 and 30. In order to properly position theribbon rolls, I provide a ribbon roll bar or block 31 removably carriedby the frame members and which in turn carries a plurality of upstandingribbon roll spacing plates or bars 32, Figs. 5 to 7.

Each of these spacers is provided with narrow substantially L-shapedgrooves 32*, and the upper part of each spacer is slotted entirelythrough in alignment with the groove or grooves. The ribbon rolls 33 areof a width to pass between the spacers and are provided with small axialprojections at each end to engage the L-shaped slots in the spacers.

When the ribbon rolls are empty, and resting upon the pulling or windingrolls 29 and 30, these projections will be in line with the lateralextensions of the L-shaped slots, which extensions are inclined upwardlyas shown at 32". This enables the fresh empty ribbon will be raiseduntil its axial projection is out of line with the branch slot and willconsequently be held against accidental removal. As the windingcontinues, the spools or rolls will rise till their central eyes alignwith the through slots in the spacers at which time (the spools beingfull) a skewer may be passed through the spool eyes and all lifted outtogether.

In order to enable the ribbons on the filled spools to be easilyseparated from the stock in the machine, and such stock readily attachedto fresh spools, I provide the following means.

Adjacent the roll 29 I provide two juxtaposed plates'34 and 35 (Figs. 1and 2 and 8 to 11). Plate 34 has slots 34 across its face correspondingin width to the width of ribbons.

It is also rebated along its edge, as indicated at 34 to provide a guidefor a cutting knife. Assuming that the spools have had the requisiteamount of ribbons Wound there- 'on and been lifted out by the skewer,they are then placed on plate 34 and rolled along the same to lay theribbons in the slots 34*, f

after which the skewer is supported in the forked or slotted upper endsof brackets 36. The operator may now readily sever all the ribbons bypassing a suitable cutting knife along the rebated edge or guide 34".The rolls of ribbons on the skewer may now be removed and it will befound that the ends of the ribbon lying on plate 34 will be of theproper length to pass around a new set of ribbon rolls in re-winding.

For this purpose I provide the plate 35 above referred to, which is ofidentical construction to plate 34, except that the slots 35 are of theproper width to receive the spools or rolls 33 (usually of steel). Oneof these rolls being dropped into each slot with the spool contactingwith roll 29, the free end of each ribbon will be of such length that itmay be lifted up from plate 34 and carried over the top of thecorresponding spool and tucked into starting position, and each spoolmay be rolled up over roll 29 and dropped into the space between thespacer plates in winding position.

Plates 34 and 35 are made removable and replaceable for different Widthsof ribbon.

Having thus described my invention what I claim is: I

1. In a winding machine of the type employing a pair of spaced drivenwinding rolls, re-Winding spools adapted to be supported by and driventhrough frictional contactof said rolls and the stock wound on saidspools, ribbon guiding means comprising a plate having elongated ribbonchannels in its surface, said channels being located in a planesubstantially coincident with the tops of the re winding rolls.

2. In a winding machine of the type employing a pair of spaced drivenwinding rolls and winding spools adapted to be supported by and driventhrough frictional contact of said rolls and the stock wound on saidspools, said spools having axial projections, guide means for saidspools comprising uprights located midway of said re-winding rolls andhaving vertical slots in their juxtaposed faces to receive said spoolprojections, and having angular entrance slots adjacent the periphery ofone of the re-winding rolls. 7

3.
